Norwegian's casual and colorful collection of 16 ships come designed with the family experience in mind, with complimentary age-specific youth spaces and programming where kids can get in on everything from learning to juggle in a circus school to participating in a scavenger hunt to attending a teens-only nightclub.

New for summer 2018, those ages 12 to 17 do, too, when sailing outside of high season. Of their 14 ships, try the 4,132-passenger MSC Seaside for its for extra-fun bonus features like four waterslides; the longest zip-line at sea; two full-size bowling lanes; and a dedicated family lounge that hosts events like talent shows and a family disco.

Adventures by Disney/AmaWaterways
Disney delivers its magic touch to the Rhine River, in partnership with river cruise line AmaWaterways.
Now in its third year, Disney brings its magic touch to European waterways like the Danube, Rhine and Seine in partnership with plush river cruise line AmaWaterways.
Long the domain of the senior set, the Adventures by Disney initiative has served to reinvent the European river cruise experience for families, too, by incorporating "adventure guide" youth-specialized staff, flexible itineraries (with cool excursion options like zip-lining through the Black Forest), and kids-geared onboard programming like Disney movie nights and ice-cream parties.
Two of the line's riverboats (the 158-passenger AmaViola and AmaKristina) were purpose-built for the partnership, featuring family-friendly connecting staterooms and heated swimming pools—a rarity for river vessels.
Coolest kids' itinerary: Look out for a new Beauty and the Beast theme on 7-night Rhine River sailings in summer 2018 between Basel, Switzerland and Amsterdam (with stops in France and Germany) aboard the AmaKristina. The itinerary includes a Beauty and the Beast-inspired feast and karaoke night, as well as a stop in Riquewihr, one of the French villages that inspired the story.

Another great option for European river cruising with the clan is French cruise line CroisiEurope. The company stands out for its "Family Club" portfolio of child-friendly voyages to Portugal, Spain and Italy; international clientele (your kids can buddy up with new pals from around the world); and no minimum-age policy, allowing even the tiniest of tots to set sail. (Most lines require a minimum of six months -- and in the case of river cruise lines, it's older still: usually four years and up.)
Onboard activities include supervised pool games and a performance in the cruise's closing show. Best of all, children under 16 travel entirely for free, and two kids traveling with two fare-paying adults get a complimentary second cabin next door.
Coolest kids' itinerary: The 158-passenger MS Michelangelo embarks on select 5-night Italian summer sailings round-trip from Venice, with family-ready excursions like touring Verona (of Romeo and Juliet fame) by bike, swimming at the seaside resort of Sottomarina or cruising Venice by gondola.

Coolest kids' itinerary: The 84-passenger Safari Endeavour runs sailings in Baja Mexico's Sea of Cortez round-trip from La Paz, Mexico, between December and March.
